36 Facts About Federated Learning

What is Federated Learning?

Federated Learning is a machine learning technique that trains an algorithm across multiple decentralized devices without exchanging their data. This approach enhances privacy and security, making it a hot topic in the tech world. Let's dive into some fascinating facts about Federated Learning.

1. 01

   Federated Learning was first introduced by Google in 2016 to improve the performance of machine learning models while preserving user privacy.

2. 02

   Decentralized Training means data stays on the device, reducing the risk of data breaches.

3. 03

   Collaborative Learning allows multiple devices to contribute to a single model, making it more robust and accurate.

4. 04

   Privacy-Preserving techniques like differential privacy and secure multi-party computation are often used in Federated Learning.

How Federated Learning Works

Understanding the mechanics behind Federated Learning can be complex, but breaking it down makes it easier to grasp.

5. 05

   Local Training involves each device training a model using its own data.

6. 06

   Model Aggregation happens on a central server, which collects and averages the model updates from all devices.

7. 07

   Global Model Update is then sent back to the devices, improving their local models without sharing raw data.

8. 08

   Iterative Process continues until the model reaches the desired performance.

15. 15

    Smartphones improve predictive text and voice recognition without sending data to the cloud.

16. 16

    IoT Devices like smart home systems can learn user preferences without sharing data externally.

Challenges in Federated Learning

Despite its benefits, Federated Learning faces several challenges that need to be addressed.

17. 17

    Data Heterogeneity as data on different devices can vary significantly.

18. 18

    Communication Overhead due to frequent model updates between devices and the central server.

19. 19

    Security Risks like model poisoning attacks where malicious updates can corrupt the global model.

20. 20

    Resource Constraints on devices with limited computational power and battery life.

Future of Federated Learning
